The Seahawks play the Rams next Monday and could be facing Kellen Clemens, not Sam Bradford.
To update, a few other reporters have confirmed this. Sounds like Bradford is out for the year. Clemens has seven touchdowns and 13 interceptions in his career. The Seahawks lead the league with 11 interceptions.
Source: Rams QB Sam Bradford has torn ACL.
